Section 6.1 Title Insurance. Purchaser acknowledges that Seller has delivered to Purchaser, and Purchaser has received, a copy of Seller’s current title policy for the Property, and Purchaser will obtain and deliver to Seller prior to the expiration of the Evaluation Period a copy of a commitment for title insurance (the “Title Commitment”) from the Title Company with respect to the Property. If the Title Commitment discloses exceptions to title which are both (A) not included within the list of permitted title matters listed on Exhibit C attached hereto and made a part hereof and (B) material and adverse to Purchaser in Purchaser’s good faith business judgment (any such exception being referred to herein as an “Unpermitted Title Exception”), then Purchaser shall have the right to give Seller notice of any such Unpermitted Title Exception on or prior to the date which is five (5) days after Purchaser’s receipt of the title commitment (the “Title Objection Out Date”). Any matters revealed by the Title Commitment that are not objected to by Purchaser on or prior to the Title Objection Out Date shall be deemed “Permitted Title Exceptions”. In addition, any matters revealed by the Title Commitment that do not constitute Unpermitted Title Exceptions, regardless of whether Purchaser objects thereto, shall constitute Permitted Title Exceptions. Seller shall have five (5) days following the receipt of any such notice in which to give Purchaser notice that Seller will either (a) cause such Unpermitted Title Exception(s) to be deleted as an exception from the Title Commitment or insured against by the Title Company or (b) not cause such Unpermitted Title Exception(s) to be deleted as an exception from the Title Commitment or insured against by the Title Company (without payment of additional charge or premium by either party); if Seller gives notice pursuant to clause (a), then Seller will cause such Unpermitted Title Exception(s) to be deleted from the Title Commitment or cause the Title Company to give affirmative insurance in favor of Purchaser with respect to such Unpermitted Title Exception(s) prior to the Closing Date (and Seller shall have the right to adjourn the Closing Date for up to four (4) days in order to effectuate same). If Seller (i) fails to give any such notice within said five (5) day period, or (ii) gives notice pursuant to clause (b) above, then Purchaser will have three (3) Business Days following the earlier of the expiration of such five (5) day period or the giving of such notice by Seller in which to elect to either (X) terminate this Agreement or (Y) waive the right to terminate this Agreement as a result of any such Unpermitted Title Exception(s), which election must be made by the giving of notice thereof to Seller within said three (3) Business Day period. If Purchaser fails to deliver such notice terminating this Agreement pursuant to clause (X) above within said three (3) Business Day period, then Purchaser shall be deemed to have waived its right to terminate this Agreement. If Purchaser elects to waive, or is deemed to have waived, the right to terminate this Agreement as aforesaid, then any Unpermitted Title Exceptions previously objected to by Purchaser shall become “Permitted Title Exceptions”. If Purchaser terminates this Agreement as aforesaid, then Seller and Purchaser shall direct the Title Company to return the Earnest Money Deposit to Purchaser, and neither party shall have any further obligation under this Agreement or the Section 2.2(b) Transactions, except that the obligations of the parties under the Termination Surviving Obligations shall survive.

may, at Purchaser’s option within the Evaluation Period, obtain, and deliver to Seller a copy of, an updated survey of the Property certified to Purchaser and the Title Company (the existing survey or the updated survey, as applicable, “Survey”). If Purchaser does not obtain an updated survey, then Seller, upon request by Purchaser, shall execute and deliver at Closing a survey affidavit of no change. If the Survey discloses conditions which are both (A) not included within the list of permitted title matters listed on Exhibit C attached hereto and made a part hereof and (B) material and adverse to Purchaser in Purchaser’s good faith business judgment (any such exception being referred to herein as an “Unpermitted Survey Condition”, then Purchaser shall have the right to give Seller notice of any such Unpermitted Survey Condition on or prior to the date which is five (5) days after Purchaser’s receipt of the Survey (the “Survey Objection Out Date”). Any matters revealed by the Survey that are not objected to by Purchaser on or prior to the Survey Objection Out Date shall be deemed “Permitted Survey Conditions”. In addition, any matters revealed by the Survey that do not constitute Unpermitted Survey Conditions, regardless of whether Purchaser objects thereto, shall constitute Permitted Survey Conditions. Seller shall have five (5) days following the receipt of any such notice in which to give Purchaser notice that Seller will either (a) cause such Unpermitted Survey Conditions(s) to be removed from the Survey or insured against by the Title Company or (b) not cause such Unpermitted Survey Conditions(s) to be removed from the Survey or insured against by the Title Company (without payment of additional charge or premium by either party); if Seller gives notice pursuant to clause (a), then Seller will cause such Unpermitted Survey Conditions(s) to be deleted from the Survey, or cause the Title Company to give affirmative insurance in favor of Purchaser with respect to such Unpermitted Survey Conditions(s) prior to the Closing Date (and Seller shall have the right to adjourn the Closing Date for up to four (4) days in order to effectuate same).

If Purchaser terminates this Agreement as aforesaid, then Seller and Purchaser shall direct the Title Company to return the Earnest Money Deposit to Purchaser, and neither party shall have any further obligation under this Agreement or the Section 2.2(b) Transactions, except that the obligations of the parties under the Termination Surviving Obligations shall survive.

Section 6.3 Updates. In the event that any update of the Title Commitment or the Survey shows any new matters or conditions to which Purchaser does not desire to take subject, Purchaser shall deliver notice thereof to Seller prior to the date three (3) Business Days after Purchaser receives such update of the Title Commitment or the Survey (and if Purchaser fails to deliver such notice within such three (3) Business Day period, then Purchaser shall be deemed to have accepted such matters or conditions as Permitted Title Exceptions or Permitted Survey

(i) Utility charges payable by Seller, if any, including, without limitation, electricity, water charges and sewer charges. If there are meters on the Real Property, Seller will cause readings of all said meters to be performed not more than five (5) days prior to

the Closing Date, and a per diem adjustment shall be made for the days between the meter reading date and the Closing Date based on the most recent meter reading.

(ii) License fees and any other amounts payable under the AT&T Wireless License, if any.

(iii) Real estate taxes due and payable for the calendar year. If the Closing Date shall occur before the tax rate is fixed, the apportionment of real estate taxes shall be upon the basis of the tax rate for the preceding year applied to the latest assessed valuation.

(iv) Any unconfirmed assessments will be satisfied in full by Seller at Closing.

Seller will be charged and credited for the amounts of all of the Proration Items relating to the period up to and including the Proration Time, and Purchaser will be charged and credited for all of the Proration Items relating to the period after the Proration Time. The estimated Closing prorations shall be set forth on a preliminary closing statement to be prepared by Seller and submitted to Purchaser prior to the Closing Date (the “Closing Statement”). The Closing Statement, once agreed upon, shall be signed by Purchaser and Seller. The prorations shall be paid at Closing by Purchaser to Seller (if the prorations result in a net credit to Seller) or by Seller to Purchaser (if the prorations result in a net credit to Purchaser) by increasing or reducing the cash to be delivered by Purchaser in payment of the Purchase Price at the Closing. If the actual amounts of the Proration Items are not known as of the Closing Date, the prorations will be made at Closing on the basis of the best evidence then available; thereafter, when actual figures are received, re-prorations will be made on the basis of the actual figures, and a final cash settlement will be made between Seller and Purchaser. No prorations will be made in relation to insurance premiums, and Seller’s insurance policies will not be assigned to Purchaser. Final readings and final billings for utilities will be made if possible as of the Closing Date, in which event no proration will be made at the Closing with respect to utility bills. Seller will be entitled to all deposits presently in effect with the utility providers, and Purchaser will be obligated to make its own arrangements for any deposits with the utility providers. The provisions of this Section 10.4(a) will survive the Closing for twelve (12) months.

Section 10.5 Costs of Title Company and Closing Costs. Costs of the Title Company and other Closing costs incurred in connection with the Closing will be allocated as follows:

(a) Seller shall pay (i) Seller’s attorney’s fees, (ii) all transfer and conveyance taxes and (iii) one-half (1/2) of escrow fees, if any.

(b) Purchaser shall pay (i) the costs of recording the Deed to the Property and all other documents; (ii) the cost of the premium for the Title Policy and all title searches; (iii) all costs of any additional coverage under the Title Policy or endorsements or deletions to the Title Policy that are desired by Purchaser, and not required to be provided by Seller to address title defects as may be imposed pursuant to Sections 6.1 or 6.4; (iv) all premiums and other costs for any mortgagee policy of title insurance, if any, including but not limited to any endorsements or deletions; (v) Purchaser’s attorney’s fees; (vi) one-half (1/2) of escrow fees, if any and (vii) the costs of the Survey as provided for in Section 6.2.

(c) Any other costs and expenses of Closing not provided for in this Section 10.5 shall be allocated between Purchaser and Seller in accordance with the custom in the area in which the Property is located.

ARTICLE XI

CONDEMNATION AND CASUALTY

Section 11.1 Casualty. If, prior to the Closing Date, the Real Property and Improvements are destroyed or damaged by fire or other casualty in whole or in part, Seller will notify Purchaser of such casualty and Seller shall have the option to either: (i) restore the damage prior to Closing, or (ii) proceed to Closing and provide Purchaser with an assignment of all money received or receivable under any insurance polices and, to the extent the loss or damage is not covered by insurance, or to the extent of any deductibles, Seller shall pay or credit at Closing Purchaser an amount equal to the reasonable costs of repairing or restoring the damage.

Section 11.2 Condemnation of Property.

In the event of any actual or threatened condemnation of all or any Significant Portion of the Real Property and Improvements prior to the Closing, Purchaser shall have the option to terminate this Agreement by serving written notice to Seller within thirty (30) days after receipt of notice of such condemnation. If this Agreement is terminated by Purchaser pursuant to this Section 11.2, the Earnest Money Deposit and all interest accrued thereon will be returned to Purchaser and thereafter neither Seller nor Purchaser will have any further rights or obligations to the other hereunder or with respect to the Section 2.2(b) Transactions except with respect to the Termination Surviving Obligations. If Purchaser elects not to terminate this Agreement in accordance with this Section 11.2, Seller will assign to Purchaser any and all claims for the proceeds of such condemnation or sale to the extent the same are applicable to the Property, and Purchaser will take title to the Property with the assignment of such proceeds and subject to such condemnation and without reduction of the Purchase Price. Notwithstanding anything to the contrary herein, if any eminent domain or condemnation proceeding is instituted (or notice of same is given) solely for the taking of any subsurface rights for utility easements or for any right-of-way easement, and the surface may, after such taking, be used in substantially the same manner as though such rights have not been taken, Purchaser will not be entitled to terminate this Agreement as to any part of the Property, but any award resulting therefrom will be assigned to Purchaser at Closing and will be the exclusive property of Purchaser upon Closing.

ARTICLE XII

CONFIDENTIALITY

Section 12.1 Confidentiality. Seller and Purchaser each expressly acknowledge and agree that the transactions contemplated by this Agreement and the terms, conditions, and negotiations concerning the same will be held in the strictest confidence by each of them until Closing and will not be disclosed by either of them except to their respective legal counsel, accountants, consultants, officers, partners, directors, and shareholders, and except and only to the extent that such disclosure may be necessary for their respective performances hereunder. Purchaser further acknowledges and agrees that, unless and until the Closing occurs, all information obtained by Purchaser in connection with the Property will not be disclosed by

Purchaser to any third persons without the prior written consent of Seller, except as otherwise provided in this Agreement. Nothing contained in this Article XII will preclude or limit either party to this Agreement from disclosing or accessing any information otherwise deemed confidential under this Article XII response to lawful process or subpoena or other valid or enforceable order of a court of competent jurisdiction or any filings with governmental authorities required by reason of the transactions provided for herein pursuant to an opinion of counsel. Nothing in this Article XII will negate, supersede or otherwise affect the obligations of the parties under the Right of Access and Confidentiality Agreement. In addition, prior to or as a part of the Closing, any press release with respect to the sale contemplated herein or any matters set forth in this Agreement will be made only in the form approved by both parties and their respective counsel, which approval shall not be unreasonably withheld or delayed. The parties and their respective counsel hereby approve the post-closing issuance of a press release substantially in the form attached hereto as Exhibit M, attached hereto and made a part hereof. The provisions of this Article XII will survive any termination of this Agreement.

ARTICLE XIII

REMEDIES

Section 13.1 Default by Seller. In the event the Closing and the transactions contemplated hereby do not occur as herein provided by reason of any default of Seller, Purchaser may, as Purchaser’s sole and exclusive remedy, elect by written notice to Seller within fifteen (15) Business Days following the Scheduled Closing Date, either of the following: (a) terminate this Agreement, in which event Purchaser will receive from the Escrow Agent the Earnest Money Deposit together with all interest accrued thereon and Seller pay to Purchaser an amount equal to its reasonable out-of-pocket expenses incurred by Purchaser such amount not to exceed Five Hundred Thousand Dollars ($500,000.00), whereupon Seller and Purchaser will have no further rights or obligations under this Agreement, except with respect to the Termination Surviving Obligations; or (b) seek to enforce specific performance of Seller’s obligations hereunder. Notwithstanding the foregoing, in the event the Closing and the transactions contemplated hereby do not occur as herein provided by reason of any willful material default of Seller, Purchaser and Seller agree that Purchaser may, as Purchaser’s sole and exclusive remedy, elect by written notice to Seller within thirty (30) Business Days following the Scheduled Closing Date, either of the following: (a) terminate this Agreement, in which event Purchaser will receive from the Escrow Agent the Earnest Money Deposit together with all interest accrued thereon and Seller shall pay to Purchaser an amount equal to Five Hundred Thousand Dollars ($500,000.00) as the full, agreed and liquidated damages for Seller’s default and failure to complete the sale of the Property, whereupon this Agreement will terminate and Seller and Purchaser will have no further rights or obligations hereunder, except with respect to the Termination Surviving Obligations; or (b) seek to enforce specific performance of Seller’s obligations hereunder. Except as provided in this Section with regard to out-of pocket expenses and the liquidated damages in the event of a willful material default by Seller, Purchaser expressly waives its rights to seek damages in the event of Seller’s default hereunder. Purchaser shall be deemed to have elected to terminate this Agreement and receive back the Earnest Money Deposit if Purchaser fails to file suit for specific performance against Seller in a court having jurisdiction in the county and state in which the Property is located or provide Seller with notice of a willful material default, on or before ninety (90) days following the Scheduled Closing Date.

Section 13.2 Default by Purchaser. In the event the Closing and the consummation of the transactions contemplated herein do not occur as provided herein by reason of any default of Purchaser, Purchaser and Seller agree it would be impractical and extremely difficult to fix the damages which Seller may suffer. Purchaser and Seller hereby agree that (a) an amount equal to the Earnest Money Deposit, together with all interest accrued thereon, is a reasonable estimate of the total net detriment Seller would suffer in the event Purchaser defaults and fails to complete the purchase of the Property, and (b) such amount will be the full, agreed and liquidated damages for Purchaser’s default and failure to complete the purchase of the Property, and will be Seller’s sole and exclusive remedy (whether at law or in equity) for any default of Purchaser resulting in the failure of consummation of the Closing, whereupon this Agreement will terminate and Seller and Purchaser will have no further rights or obligations hereunder, except with respect to the Termination Surviving Obligations. The payment of such amount as liquidated damages is not intended as a forfeiture or penalty but is intended to constitute liquidated damages to Seller. Notwithstanding the foregoing, nothing contained herein will limit Seller’s remedies at law, in equity or as herein provided in the event of a breach by Purchaser of any of the Termination Surviving Obligations.

ARTICLE XIV

ASSIGNMENT AND BINDING EFFECT

Section 15.1 Assignment; Binding Effect. The provisions hereof shall inure to the benefit of, and shall be binding upon, the heirs, executors, administrators, successors and assigns of the respective parties; provided, however, Purchaser may not assign this Agreement or any of Purchaser’s rights hereunder to any person or entity other than to a Permitted Assignee (as hereinafter defined). No permitted assignment of this Agreement shall relieve Purchaser from any of its obligations hereunder. As used herein, a “Permitted Assignee” shall mean an Affiliate of Purchaser. As used herein, an “Affiliate” shall refer to an entity that is controlled by the same entity that controls Purchaser, is controlled by Purchaser or Mack-Cali Realty L.P., or controls Purchaser. The terms “control,” “controlled by,” or “in common control with” shall mean ownership of (i) more than fifty percent (50%) of the outstanding voting stock of a corporation (or other equity and control interest if not a corporation), or (ii) the possession of power to direct

or cause the direction of the management and policy of such corporation or other entity, whether through the ownership of voting securities, by statute, or according to the provisions of a contract.

ARTICLE XVI

BROKERAGE

Section 16.1 Brokers. Purchaser and Seller represent that they have not dealt with any brokers, finders or salesmen, in connection with this transaction and agree to indemnify, defend and hold each other harmless from and against any and all loss, cost, damage, liability or expense, including reasonable attorneys’ fees, which either party may sustain, incur or be exposed to by reason of any claim for fees or commissions made through the other party. The provisions of this Article XVI will survive any Closing or termination of this Agreement.

ARTICLE XVII

ESCROW AGENT

Section 17.1 Escrow.

(a) Escrow Agent will hold the Earnest Money Deposit in escrow in an interest bearing account of the type generally used by Escrow Agent for the holding of escrow funds until the earlier of (i) the Closing, or (ii) the termination of this Agreement in accordance with any right hereunder. In the event Purchaser has not terminated this Agreement by the end of the Evaluation Period, the Earnest Money Deposit shall be non-refundable to Purchaser, but shall be credited against the Purchase Price at the Closing. All interest earned on the Earnest Money Deposit shall be paid to the party entitled to the Earnest Money Deposit. In the event this Agreement is terminated prior to the expiration of the Evaluation Period or as otherwise provided for in accordance with the terms and provisions of this Agreement, the Earnest Money Deposit and all interest accrued thereon will be returned by the Escrow Agent to the Purchaser. In the event the Closing occurs, the Earnest Money Deposit and all interest accrued thereon will be released to Seller, and Purchaser shall receive a credit against the Purchase Price in the amount of the Earnest Money Deposit, without the interest. In all other instances, Escrow Agent shall not release the Earnest Money Deposit to either party until Escrow Agent has been requested by Seller or Purchaser to release the Earnest Money Deposit and has given the other party five (5) Business Days to dispute, or consent to, the release of the Earnest Money Deposit. Seller represents that its tax identification number, for purposes of reporting the interest earnings, is 13-4924710. Purchaser represents that its tax identification number, for purposes of reporting the interest earnings, is 22-3305147.

(b) Escrow Agent shall not be liable to any party for any act or omission, except for bad faith, gross negligence or willful misconduct, and the parties agree to indemnify Escrow Agent and hold Escrow Agent harmless from any and all claims, damages, losses or expenses arising in connection herewith. The parties acknowledge that Escrow Agent is acting solely as stakeholder for their mutual convenience. In the event Escrow Agent receives written notice of a dispute between the parties with respect to the Earnest Money Deposit and the interest earned thereon (the “Escrowed Funds”), Escrow Agent shall not be bound to release and deliver the Escrowed Funds to either party but may either (i) continue to hold the Escrowed Funds until

otherwise directed in a writing signed by all parties hereto or (ii) deposit the Escrowed Funds with the clerk of any court of competent jurisdiction. Upon such deposit, Escrow Agent will be released from all duties and responsibilities hereunder. Escrow Agent shall have the right to consult with separate counsel of its own choosing (if it deems such consultation advisable) and shall not be liable for any action taken, suffered or omitted by it in accordance with the advice of such counsel.

I Escrow Agent shall not be required to defend any legal proceeding which may be instituted against it with respect to the Escrowed Funds, the Property or the subject matter of this Agreement unless requested to do so by Purchaser or Seller and is indemnified to its satisfaction against the cost and expense of such defense. Escrow Agent shall not be required to institute legal proceedings of any kind and shall have no responsibility for the genuineness or validity of any document or other item deposited with it or the collectibility of any check delivered in connection with this Agreement. Escrow Agent shall be fully protected in acting in accordance with any written instructions given to it hereunder and believed by it to have been signed by the proper parties.

ARTICLE XVIII

MISCELLANEOUS

Section 18.1 Waivers. No waiver of any breach of any covenant or provisions contained herein will be deemed a waiver of any preceding or succeeding breach thereof, or of any other covenant or provision contained herein. No extension of time for performance of any obligation or act will be deemed an extension of the time for performance of any other obligation or act.

Section 18.2 Recovery of Certain Fees. In the event a party hereto files any action or Suit against another party hereto by reason of any breach of any of the covenants, agreements or provisions contained in this Agreement, then in that event the substantially prevailing party will be entitled to have and recover certain fees from the other party including all reasonable attorneys’ fees and costs resulting therefrom. For purposes of this Agreement, the term “attorneys’ fees” or “attorneys’ fees and costs” shall mean the fees and expenses of counsel to the parties hereto, which may include printing, photocopying, duplicating and other expenses, air freight charges, and fees billed for law clerks, paralegals and other persons not admitted to the bar but performing services under the supervision of an attorney, and the costs and fees incurred in connection with the enforcement or collection of any judgment obtained in any such proceeding.

Whenever required by the context of this Agreement, the singular will include the plural and the masculine will include the feminine and vice versa. This Agreement will not be construed as if it had been prepared by one of the parties, but rather as if both parties had prepared the same. All exhibits and schedules referred to in this Agreement are attached and incorporated by this reference, and any capitalized term used in any exhibit or schedule which is not defined in such exhibit or schedule will have the meaning attributable to such term in the body of this Agreement.

Section 18.5 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, all of the other conditions and provisions of this Agreement will nevertheless remain in full force and effect, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to either party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto will negotiate in good faith to modify this Agreement so as to reflect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 18.6 Entire Agreement. This Agreement is the final expression of, and contains the entire agreement between, the parties with respect to the subject matter hereof, and supersedes all prior understandings with respect thereto. This Agreement may not be modified, changed, supplemented or terminated, nor may any obligations hereunder be waived, except by written instrument, signed by the party to be charged or by its agent duly authorized in writing, or as otherwise expressly permitted herein or in the Right of Access and Confidentiality Agreement.

Section 18.7 Governing Law. THIS AGREEMENT WILL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE PROPERTY IS LOCATED, WITHOUT GIVING EFFECT TO ITS CONFLICT OF LAWS RULES.

Section 18.12 Limitations on Benefits. It is the explicit intention of Purchaser and Seller that no person or entity other than Purchaser and Seller and their permitted successors and assigns is or shall be entitled to bring any action to enforce any provision of this Agreement against any of the parties hereto, and the covenants, undertakings and agreements set forth in this Agreement shall be solely for the benefit of, and shall be enforceable only by, Purchaser and Seller or their respective successors and assigns as permitted hereunder.

THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY PURCHASER AND SELLER, AND IS INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A TRIAL BY JURY WOULD OTHERWISE ACCRUE.
